What you need is OpenKiosk, an extension to Mozilla that we developed
at Brooklyn Museum, with contracted help from MozDevGroup. Check it
out at:

Note that there is an official Mozilla extension for this in the
regular place, but it's hard to get Mozilla to update those pages and
so the version there is probably out of date.
